COOLING DEVICE.

f Application filed July 8, 1924. vSerial No. 724,811.

To all lwhom t may concern:

Be it known that I, FRANK W. STEERE, a citizen of the United States, and residentof the city of Highland Park, county ofWayne, and State of Michigan, have invented certain, new and useful Improvements in Cooling Devices, of' which the following is a specification, reference being had to the accompanying drawings.

It is the primary object of my invention to provide a cooling device of simple and economical construction. It is a ifurther object to provide new and useful means for making and assembling a strip between the various layers of the parallel pipes, which strip is generally referred to as a wind strip and serves the purpose of causing water flowing over the cooler to more evenly and more generally strike the pipes of the cooler.

IVith the above and other objects in view, my invention consists in the arrangement, combination and construction of the various parts of my improved device, as described in the specification, claimed in my claims and shown in the accompanying drawings, in which:

Fig. 1 is a front elevation of my improved coil.

Fig. 2 is an end elevation of the same.

Fig. 3 is a sectional view taken through two of the coils and showing the assembly of the wind strip thereto.

Fig. 11 is a detailed sectional view showing, before final assembly, my improved clips for securing the wind strips in place.

I have shown a cooler arrangement consisting of two end members or headers 5 and 6, into which a plurality of pipes 7 extend. The ends of the pipes may be secured in place in the headers by expanding them much in the same nature as boiler flues are secured in place. The pipes are connected together in series of two as shown in the cut away portion inv Fig. 1 by disposing baffle plates 20 in the headers so as to cause t-he flow of liquid in an adjacent pair of pipes to alternate, as indicated by the arrows in Fig. 1. Plugs 8 are disposed on the outer ends of the headers, one opposite the end of each pipe 7 so that old pipes may be removed and new ones inserted when desired and also in order to provide means for cleaning the pipes when desired.

An intermediate member 9 is provided with supporting rods or bolts 10, extending between the pipes 7 to prevent sagging thereof intermediate their ends.

Troughs 11 and 12 are secured by means of brackets 13 and 14 secured thereto and supported by bolts 21 and 22 on the ends thereof and a central bolt 23. The level of the troughs may be adjusted by means of a pair of nuts 24 and 25 provided on each of the bolts 21, 22 and 23. The troughs 11 and 12 are provided with a plurality of openings 26 through which the water passes and continues downwardly over the outer faces of the trough until it reaches the serrations 27 from whence it will drip over the top pipe 7 and continue over the remainder of the pipes.

Between the pipes 7 are disposed strips 15 which are held against displacement by pairs of clips 16 and 17 secured to the strips 15 by means of rivets 18 or by welding the clips to the. strips.

In assembling the strips to the pipes, the clip 16 is originally formed in its finished shape, but the clip 17 is formed of somewhat U shaped formation, as shown in Fig. il. The clip 17 is then pushed between the pipes 7 until the clip 16 bea-rs against the sides of the pipe and then it is pressed outwardly to assume.substantially the same shape as the clip 16. The strips together with the clips, may be sherardized, galvanized or otherwise rustproofed, in order to make them impervious to the elements or action of water.

It is obvious that various changes may be made in the arrangement, combination and construction of the various parts of my improved device without departing from the spirit of my invention, and it is my intention to Cover by my claim such changes as may be reasonably included within the scope thereof.

lfvlhat I claim is:

A device of the class described comprising a header, a plurality of pipes arranged in parallel relation extended into saidiheader and connected in series with each other, a plurality of plugs in said header opposite the ends of said pipes, a plurality of strips extended between said pipes anda pair of outwardly flared clips secured to each of said strips, one on either side of and bearing against adjacent sides of two of said pipes for securing said strips.

FRANK W. STEERE.
